Heating?

Many thank Iain, appreciate your advice. I have a rep from Brit Gas coming Friday morning and one from Swale Htg in the afternoon, to quote for room stat installation. (Brit Gas did the rad stats and I think I was well ripped off on cost, hence a second quote from an independent but well known company so I can compare prices). Compliments of the season.

Right, boiler stat does not kind of work like that.... the most efficient way of running a heating system is with the boiler stat on pretty high and then have a room stat to switch the boiler off when the room reaches your comfort level 22 degrees etc.
This is more economical as the boiler will come on once for a longer period to try and satisfy the room stat (which you aint got) then the stat will turn the boiler off.
If you have the boiler set to low, it will cycle on and off all day trying to reach a temperature that it cant achieve as the boiler tells it to turn off repeatedly all day.

Consider getting a room stat.

The rad valves, trv's are marked * to 5 for example each step indicating a set degree ie number 3 approx 22 degrees for examples sake. These settings make zero difference to how hot the radiator gets but tell the radiator to turn off when the room reaches the set level.

so if you have it on frost which might be 5 degrees the radiator will still come on if the room is below 5 degrees to allow the room to warm up and prevent problems and bursts etc. it will come on and get just as hot as a rad set to 5 but will turn off when room reaches 5 degrees where as rad set to 5 in different room might not turn off til 30 degree room temp.

hope that makes a slight bit sense and the temps are just guidelines :-)
